The sources further revealed that this is the second visit of Prime Minister Shehbaz Sharif to the KSA within one month.
During the visit to Saudi Arabia, the PM is expected to hold consultations on key regional and international developments, signalling continued diplomatic engagement between the two countries.
The visit follows much-anticipated talks in Islamabad, which ran from Saturday into early Sunday and were the first direct US-Iran meeting in more than a decade and the highest-level discussions since Iran's 1979 Islamic Revolution.
The prime minister will be accompanied by Chief of Defence Forces Field Marshal Asim Munir, Deputy Prime Minister and Foreign Minister Senator Ishaq Dar, and Special Assistant Syed Tariq Fatemi.
Finance Minister Muhammad Aurangzeb is also expected to join the delegation in Riyadh, subject to the completion of his ongoing visit to the United States.
